The use of dependent views is invaluable in a MEP model when systems cross match lines. By creating two dependent views of level 1, one can represent the East wing and the other the West wing. Because the two dependent view will share the annotations of the parent view along with all the view settings, systems can be designed and documented in an overall view while the sheet (dependent) views reflect the big picture.
What happens when you want to move on to level 2, 3, and 4? Right click on the the level 1 overall view and select "Apply Dependent Views".
This will bring up a dialog to select views to apply the same dependent views to. The beauty part? The same crop regions are applied to each of the other selected levels. so sweet!
If for some reason you need to make a dependent view and independent view, right click has got you covered again. This time select "Convert to Independent View".
